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

a ;-list of macros to define (-DFOO=bar).

CMAKE_REQUIRED_INCLUDES

a ;-list of header search paths to pass to the compiler.

CMAKE_REQUIRED_LINK_OPTIONS

a ;-list of options to add to the link command.

CMAKE_REQUIRED_LIBRARIES

a ;-list of libraries to add to the link command. See policy CMP0075.

CMAKE_REQUIRED_QUIET

execute quietly without messages.

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