# 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.

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``
