CMake interprets an elseif() with no arguments as elseif(FALSE),
resulting in the elseif() block not being executed. That is not what
was intended here. Change the empty elseif() to an else() as it was
intended.

Closes https://github.com/curl/curl/pull/3739
With CMAKE_TRY_COMPILE_TARGET_TYPE set to STATIC_LIBRARY, the try_compile()
(which is used by check_c_source_compiles()) will build static library
instead of executable. This avoids linking additional libraries in and thus
speeds up those checks a little.
This commit also avoids #3743 (GSSAPI build errors) on itself with cmake
3.6 or above. That issue was fixed separately for all versions.
Ref: #3744
Use 'GNUInstallDirs' standard module to set destinations of installed
files.
Use uppercase "CURL" names instead of lowercase "curl" to match standard
'FindCURL.cmake' CMake module:
* https://cmake.org/cmake/help/latest/module/FindCURL.html
Meaning:
* Install 'CURLConfig.cmake' instead of 'curl-config.cmake'
* User should call 'find_package(CURL)' instead of 'find_package(curl)'
Use 'configure_package_config_file' function to generate
'CURLConfig.cmake' file. This will make 'curl-config.cmake.in' template
file smaller and handle components better. E.g. current configuration
report no error if user specified unknown components (note: new
configuration expects no components, report error if user will try to
specify any).

Currently CMake cannot detect Brotli support. This adds detection of the
libraries and associated header files. It also adds this to the
generated config.
Closes#2392
The config files define curl and libcurl targets as imported targets
CURL::curl and CURL::libcurl. For backward compatibility with CMake-
provided find-module the CURL_INCLUDE_DIRS and CURL_LIBRARIES are
also set.
Closes#1879
Detect support for compiler symbol visibility flags and apply those
according to CURL_HIDDEN_SYMBOLS option.
It should work true to the autotools build except it tries to unhide
symbols on Windows when requested and prints warning if it fails.

Fix the check code to pass 5 arguments instead of 6. This typo was
introduced by commit aebfd4cfbf (cmake: fix gethostby{addr,name}_r in
CurlTests, 2014-10-31).
Set CMAKE_REQUIRED_DEFINITIONS to include definitions needed to get
the winsock2 API from windows.h. Simplify the order of checks to
avoid extra conditions.
Use check_include_file instead of check_include_file_concat to look
for OpenSSL headers. They do not need to participate in a sequence
of dependent system headers. Also they may cause winsock.h to be
included before ws2tcpip.h, causing the latter to not be detected
in the sequence.

Remove use of an old hack that takes advantage of the auto-dereference
behavior of the if() command to detect if a variable is defined. The
hack has the form:
if("${VAR} MATCHES "^${VAR}$")
where "${VAR}" is a macro argument reference. Use if(DEFINED) instead.
This also avoids warnings for CMake Policy CMP0054 in CMake 3.1.
Revert commit 2257deb502 (Cmake: Avoid cycle directory dependencies,
2014-08-22) and add a comment explaining the purpose of the original
code.
The check_library_exists_concat macro is intended to be called multiple
times on a sequence of possibly dependent libraries. Later libraries
may depend on earlier libraries when they are static. They cannot be
safely linked in reverse order on some platforms.

Revert commit 1269df2e3b (Cmake: Don't check for all headers each
time, 2014-08-15) and add a comment explaining the purpose of the
original code.
The check_include_file_concat macro is intended to be called multiple
times on a sequence of possibly dependent headers. Later headers
may depend on earlier headers to provide declarations. They cannot
be safely included independently on some platforms.
For example, many POSIX APIs document including sys/types.h before some
other headers. Also on some OS X versions sys/socket.h must be included
before net/if.h or the check for the latter will fail.

Otherwise Curl_gethostname always fails. Windows has gethostname
since Vista according to
http://msdn.microsoft.com/en-us/library/ms738527%28VS.85%29.aspx, but
accordings to byte_bucket's VC 2005 documentation, it is available even
in Windows 95. (possibly after installing a Platform SDK, the
Windows Server 2003 SP1 Platform SDK should be sufficient).

There were several -Wunused warnings and one duplicate macro definition.
The EXTRA_DEFINES variable of the CurlCheckCSources macro was being
abused ("__unused1\n#undef inline\n#define __unused2", seriously?) to
insert extra C code. Avoid this broken abstraction and use cmake's
check_c_source_compiles directly (works fine with CMake 2.8, maybe
even cmake 2.6).
After cleaning up all related variables (EXTRA_DEFINES,
HEADER_INCLUDES, auxiliary headers_hack), also remove a duplicate
add_headers_include macro and remove duplicate header additions before
the struct timeval check.
Oh, and now the code is converted to use CheckCSourceRuns and
CheckCSourceCompiles, the two curl-specific helpers can be removed.
Unfortunately, the cmake output is now slightly more verbose. Before:
Performing Test int send(int, const void *, size_t, int) (curl_cv_func_send_test)
Performing Test int send(int, const void *, size_t, int) (curl_cv_func_send_test) - Failed
Since check_c_source_compiles prints the varname, now you see:
Performing Test curl_cv_func_send_test
Performing Test curl_cv_func_send_test - Failed
Tested: int send(int, const void *, size_t, int)
Compared cmake output with each other using vimdiff, no functional
differences were found. Tested with GCC 4.9.1 and Clang 3.5.0.
