# In CMake up to 2.8.12, pkg_check_modules() sets:

# <XPREFIX>_LIBRARIES, which is a list of library names to which, on
|
|
# a UN*X, -l can be prefixed - i.e., names, without extensions,
|

# rather than full paths to the file.
|
|
# <XPREFIX>_LIBRARY_DIRS, which is a list of paths to directories
|
|
# containing the libraries, to which, on a UN*X, -L can be
|
|
# prefixed.
|
|
# <XPREFIX>_LDFLAGS, which is a list of *all* required linker flags
|

|
|
# than -l and -L flags

#
|

# At least as of CMake 2.8.6, it does so by checking the size of

|
# "void *" in C, setting CMAKE_C_SIZEOF_DATA_PTR based on that,
|
|
# setting CMAKE_SIZEOF_VOID_P to that, and then checking the size
|

# of "void *" in C++, setting CMAKE_CXX_SIZEOF_DATA_PTR based on

|
# that, and then setting CMAKE_SIZEOF_VOID_P to *that*.

|

# If you set an architecture flag such as -m32 or -m64 in CFLAGS

# will ensue.

# 64-bit, and Oracle Studio's C++ compiler, which will default to

# building 32-bit, the size for C++ will win, and, again, hilarity

#
|

# So we make sure both languages have the same pointer sizes with
