[Cmake] Searching for the header files

[Bill Hoffman]

Yes, there is.
Modules/CheckIncludeFileCXX.cmake
Modules/CheckIncludeFile.cmake


Those files define macros that use try-compile with the compiler
to test for the existence of header files.

For example:

INCLUDE(${CMAKE_ROOT}/Modules/CheckIncludeFileCXX.cmake)
CHECK_INCLUDE_FILE_CXX("sstream" CMAKE_HAS_ANSI_STRING_STREAM)

BTW, there are some STL and STD tests in the modules directory,
like these:

INCLUDE(${CMAKE_ROOT}/Modules/TestForSTDNamespace.cmake)
INCLUDE(${CMAKE_ROOT}/Modules/TestForANSIForScope.cmake)
