FindICU when used natively (i.e. without Android.cmake, compilation for
pc) uses PkgConfig. Old code would only check the first depedency
returned by PkgConfig as ${PC_ICU_${MOD_NAME}_LIBRARY} would already be
set for the remaing cycles, and no new find_library would be performed.
This resulted in libicui18n being included thrice, but depedencies uc
and data being ommited.
This means we have RTL support again with ICU 58+. It makes use of:
- ICU for bidi-itemization
- ICU for script-itemization
- OpenTTD for style-itemization
- harfbuzz for shaping
CMake works on all our supported platforms, like MSVC, Mingw, GCC,
Clang, and many more. It allows for a single way of doing things,
so no longer we need shell scripts and vbs scripts to work on all
our supported platforms.
Additionally, CMake allows to generate project files for like MSVC,
KDevelop, etc.
This heavily reduces the lines of code we need to support multiple
platforms from a project perspective.
Addtiionally, this heavily improves our detection of libraries, etc.
