how to fix RapidJSON error?

[luckypoem]

after running "cmake -DCMAKE_BUILD_TYPE=Release ." ,i encountered the error:

...
CMake Error at CMakeLists.txt:21 (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.

Sorry for the (extremely) delayed reply. Since I didn't have time to work on this project lately, and I really didn't expect anyone to use it besides myself, I haven't been paying much attention.

It seems in the latest APT repository of Ubuntu, FindRapidJSON.cmake is not distributed with package rapidjson-dev. I'm not sure about other linux distributions, but it seems ArchLinux has it in the package rapidjson.

I'll try to include a copy of the cmake module along the source code. Then it should compile successfully.

OK so rapidjson is a header only library, and all appearances of the library headers in the source code is properly prefixed, so I guess we can just skip the find_package?

But doing so will cause a template deduction error. I'm not sure if the packaged provided by ubuntu is broken or not, but compiling the library from source works for me (on WSL).

# sudo apt install pkgconf
git clone https://github.com/Tencent/rapidjson.git
cd rapidjson
cmake .
make
sudo make install

Then cmake within this project should complete without error.

I'll leave this issue open until I can find a proper solution (or give up).

# sudo apt install pkgconf
git clone https://github.com/Tencent/rapidjson.git
cd rapidjson
cmake .
make
sudo make install

I did the install, issue still exist, so I added Findrapidjson.cmake to cmake/Modules.
