CheckIncludeFileCXX

CheckIncludeFileCXX

Provides a macro to check if a header file can be included in CXX.

CHECK_INCLUDE_FILE_CXX
CHECK_INCLUDE_FILE_CXX(<include> <variable> [<flags>])

Check if the given <include> file may be included in a CXX source file and store the result in an internal cache entry named <variable>. The optional third argument may be used to add compilation flags to the check (or use CMAKE_REQUIRED_FLAGS below).

The following variables may be set before calling this macro to modify the way the check is run:

CMAKE_REQUIRED_FLAGS
string of compile command line flags
CMAKE_REQUIRED_DEFINITIONS
list of macros to define (-DFOO=bar)
CMAKE_REQUIRED_INCLUDES
list of include directories
CMAKE_REQUIRED_QUIET
execute quietly without messages

See modules CheckIncludeFile and CheckIncludeFiles to check for one or more C headers.
