Problem with adding the lib as a submodule

[CDitzel]

I am trying to use your lib as a submodule in my CMake Project in an externalLibs directory that I call via add_subdirectory(json). CMake runs through, but when I try to compile I get a whole lot of errors along the following lines

~/project/extLibs/json/test/src/unit-json_patch.cpp:65:12: warning: missing terminating " character
CHECK(doc1.patch(patch) == R"(
^
~/project/extLibs/json/test/src/unit-json_patch.cpp:65:12: error: missing terminating " character
CHECK(doc1.patch(patch) == R"(
^~~~~~~~~~~~~~~~~~~~~~~~~~
~/project/extLibs/json/test/src/unit-json_patch.cpp:67:21: error: stray ‘\’ in program
"a": {

I cant seem to find the reason for that; i use gcc-7.2

help is deeply appreciated

Can you make sure you are using C++11?

[CDitzel]

I am sure, I am using some C++17 features and have

ADD_DEFINITIONS(
-std=c++1z
)

in my root CMakeLists.txt file

[CDitzel]

all right, it seems to work now. Apparently ccache was the culprit
I used

find_program(CCACHE_PROGRAM ccache) if(CCACHE_PROGRAM) message(STATUS ${ColourYellow} "-> Launching compiler through ccache and caching compilation outputs" ${ColourReset}) set_property(GLOBAL PROPERTY RULE_LAUNCH_COMPILE "${CCACHE_PROGRAM}") endif()

in my root CMakeLists.txt file and for reasons I dont yet fully understand that caused the compilation errors
