# We support different versions of ICU:
|
||
|
|
# - "bundled" uses source code in <source dir>/extra/icu
|
||
|
|
# - "system" (typically) uses headers/libraries in /usr/lib and /usr/lib64
|
||
|
|
# - a custom installation of ICU can be used like this
|
||
|
|
# - cmake -DCMAKE_PREFIX_PATH=</path/to/custom/icu> -DWITH_ICU="system"
|
||
|
|
# or
|
||
|
|
# - cmake -DWITH_ICU=</path/to/custom/icu>
|
||
|
|
#
|
||
|
|
# The default value for WITH_ICU is "bundled"
|
||
|
|
# set in cmake/build_configurations/feature_set.cmake
|
||
|
|
|
||
|
|
# To do: The default should probably be different depending on platform. On
|
||
|
|
# Windows, it should likely be wherever NuGet puts the libraries.
