c++ - CLion can't find CMake generated headers? -

going through cmake tutorial:

#include <iostream>  #include "src/fooconf.h" // tried: "fooconf.h"  int main() {     std::cout << foo_version_major;     return 0; } 

[error]

fatal error: src/fooconf.h: no such file or directory 

your fooconf.h header file generated in binary tree (precisely, under ${cmake_binary_dir}/src/). should issue corresponded include_directories() command use file in #include. e.g.:

cmakelists.txt

.... include_directories(${cmake_binary_dir}) add_executable(foo ${source_files}) 

src/main.cpp

.... #include "src/fooconf.h"
