# On OS X, make sure we do *NOT* find math.h in the Kernel framework,

#
|
|
# For some unknown reason, on Yosemite, math.h is included in the Kernel
|
|
# framework. That framework exists to supply headers for building
|
|
# *kernel* modules; it includes versions of C headers that are similar
|
|
# to the standard userland headers, but not similar enough to be usable
|
|
# when building userland code.
|
|
#
|
|
# Unless told not to look first in the framework paths, CMake will, on
|
|
# Yosemite, or when using the Yosemite SDK, find math.h in the Kernel
|
|
# framework, and add the header directory for the Kernel framework to
|
|
# the list of places to look for headers, causing it to pick up other
|
|
# headers from there as well. This causes the build to fail.
