Hi,
Now that THIRD_PARTY_TOOLS_HOME has been removed (see
https://github.com/OpenImageIO/oiio/pull/1604), what should we be using in
its place? CMAKE_PREFIX_PATH seems like it could be an alternative, but I
think it expects a different directory structure. I was able to get that
to work by hacking back in some of the removed code (see below), but I'm
curious what the intended way might be.
# Add all third party tool directories to the include and library paths so
# that they'll be correctly found by the various FIND_PACKAGE() invocations.
if (CMAKE_PREFIX_PATH AND EXISTS "${CMAKE_PREFIX_PATH}")
# Detect third party tools which have been successfully built using the
# lock files which are placed there by the external project Makefile.
file (GLOB _external_dir_lockfiles "${CMAKE_PREFIX_PATH}/*.d")
foreach (_dir_lockfile ${_external_dir_lockfiles})
# Grab the tool directory_name.d
get_filename_component (_ext_dirname ${_dir_lockfile} NAME)
# Strip off the .d extension
string (REGEX REPLACE "\\.d$" "" _ext_dirname ${_ext_dirname})
set (CMAKE_INCLUDE_PATH
"${CMAKE_PREFIX_PATH}/include/${_ext_dirname}" ${CMAKE_INCLUDE_PATH})
set (CMAKE_LIBRARY_PATH "${CMAKE_PREFIX_PATH}/lib/${_ext_dirname}"
${CMAKE_LIBRARY_PATH})
endforeach ()
endif ()
