Linker error when disabling the GRAPHQL_USE_RAPIDJSON option

[d7d1cd]

I tried to build the library on Linux using CMake. First, I ran the configuration step:

cmake . -B build -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DGRAPHQL_USE_RAPIDJSON=OFF -DGRAPHQL_BUILD_TESTS=OFF

Then I started the build:

cmake --build build/ -- -j$(nproc)

Compilation succeeded, but linking failed with the following error:

/usr/local/bin/ld: cannot find -lgraphqljson: No such file or directory

This error appeared multiple times for the following targets:

[ 79%] Linking CXX executable sample
[ 82%] Linking CXX executable benchmark
[ 82%] Linking CXX executable sample_nointrospection
[ 82%] Linking CXX executable learn_star_wars
[ 83%] Linking CXX executable benchmark_nointrospection
[ 89%] Linking CXX executable server
[ 95%] Linking CXX executable client

If the configuration settings allow disabling the use of RapidJSON, why isn't this accounted for in the build scripts? Why do they require this library?
