- Parameters assigned to ImageMagick::Magick++ will now follow
the 'openshot' shared-library target wherever it's linked, even in
build subdirectories that aren't children or siblings of the
location where the target was created.
- Removed the redundant code duplicating `find_package(ImageMagick)`
checks. Multiple dependency scans have only been necessary as a
workaround to overcome CMake variables' restricted scope.
Targets do not share that limitation.
FindOpenShotAudio.cmake: Enhance with targets
- Also, migrate as much config as possible from CMakeLists.txt files
to properties of IMPORTED OpenShot::Audio target (including platform-
specific configs)
- Rename to match package naming used elsewhere (official configs)
- Add IMPORTED target creation to the Find module, along with
version number detection
- Switch to lowercase variable forms (e.g. jsoncpp_FOUND)
The same old variables will be respected for setting the path, but the
PREFERRED method is defining `-DUnitTest++_ROOT=/path/to` on the
CMake command line. _ROOT variables are handled with extra intelligence
by CMake.
The find module will also attempt to locate the pkg-config file
UnitTest++.pc, and if found will import its data.
