# - Check if the function exists.

# CHECK_FUNCTION_EXISTS(FUNCTION VARIABLE)
|
|
# - macro which checks if the function exists
|
|
# FUNCTION - the name of the function
|
|
# VARIABLE - variable to store the result
|

#
|
|
# 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_LIBRARIES = list of libraries to link
