# - ow_add_private_library_dirs(dir1 ... dirN)
# Adds private link directories (directories in which to search for libraries
# e.g library path) to the current project
#
# Specifies the paths in which the linker should search for libraries
#
# Term 'private' means that link directories will be
# automatically used inside inherited projects
# See ow_add_public_library_dirs() for the 'public' version of this function
#
# GNU GCC Options for Directory Search: http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Directory-Options.html
# Microsoft Visual C++ Additional Libpath: http://msdn2.microsoft.com/en-us/library/1xhzskbe.aspx
#
# Example:
# ow_create_executable(mytest)
#
# ow_add_private_libraries(
#       #Path to FFmpeg library
#       /path/to/libavcodec
# )
#
# ow_add_private_libraries(
#       #FFmpeg library
#       libavcodec.a
# )
#
# ow_add_sources(
#       mytest.c
# )
#
# ow_create_project_binary()
#
# Output produced:
# gcc -L/path/to/libavcodec mytest.c -lavcodec -o mytest
#
# Internally ow_add_private_library_dirs() uses a variable named ${PROJECT_NAME}_PRIVATE_LIBRARY_DIRS
# It uses CMake function link_directories(), see ow_prepare_binary() for more details
