CMake Warning at CMakeLists.txt:45 (find_package):
By not providing "FindRapidJSON.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"RapidJSON", but CMake did not find one.
Could not find a package configuration file provided by "RapidJSON" with
any of the following names:
RapidJSONConfig.cmake
rapidjson-config.cmake
Add the installation prefix of "RapidJSON" to CMAKE_PREFIX_PATH or set
"RapidJSON_DIR" to a directory containing one of the above files. If
"RapidJSON" provides a separate development package or SDK, be sure it has
been installed.
CMake Warning at CMakeLists.txt:47 (message):
Rapidjson is not found, trying downloading from github, or you can install
Rapidjson first and reinstall abacus.
As #4981 , setting the environment variable should let ABACUS find rapidjson, but this is not work in previous version of ABACUS.
Expected behavior
ABACUS can be built with rapidjson after setting export CPATH='path/to/rapidjson/include':$CPATH
