I see two .cpp files, but indeed both in tests/

$ find . -name '*.cpp'
./test/benchmark/benchflatc/benchflatc.cpp
./test/monster_test_cpp/monster_test.cpp

There is already an option to enable/disable tests:

option(FLATCC_TEST "enable tests" ON)

and we already disable building tests in flatcc.mk:

# Disable build of tests and samples
FLATCC_CONF_OPTS += -DFLATCC_TEST=OFF
HOST_FLATCC_CONF_OPTS += -DFLATCC_TEST=OFF

The CMakeLists.txt needs to be fixed to only require a C++ compiler
when tests are enabled.

Best regards,

Thomas
