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.
