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.

# CMake provides a FindICU module since version 3.7.
|
|
# But it doesn't use pkgconfig, doesn't set expected variables,
|
|
# And it returns incomplete dependencies if only some modules are searched.

FindICU
|
|
-------
|
|
|
|
Finds components of the ICU library.
|
|
|
|
Accepted components are: uc, i18n, le, lx, io, data
|
|
|

Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This will define the following variables:
|
|
|
|
``ICU_FOUND``
|
|
True if components of ICU library are found.
|
|
``ICU_VERSION``
|
|
The version of the ICU library which was found.
|
|
``ICU_<c>_FOUND``
|
|
True if the system has the <c> component of ICU library.
|
|
``ICU_<c>_INCLUDE_DIRS``
|
|
Include directories needed to use the <c> component of ICU library.
|
|
``ICU_<c>_LIBRARIES``
|
|
Libraries needed to link to the <c> component of ICU library.
