"Compile Active File" does not work with an empty define

[dslijepcevic]

Brief Issue Summary

It looks like "Compile Active File" incorrectly parses empty defines from compile_commands.json. Instead of passing -DMY_DEFINE= to the compiler, it passes an empty argument.

CMakeLists.txt:

cmake_minimum_required(VERSION 3.8 FATAL_ERROR)
project(test C)
add_executable(test test.c)
target_compile_definitions(test PUBLIC MY_DEFINE=)

test.c:

int main()
{
    return 0;
}

build/compile_commands.json:

[
{
  "directory": "/proj/test/build",
  "command": "/usr/bin/cc -DMY_DEFINE=\"\"  -g   -o CMakeFiles/test.dir/test.c.o   -c /proj/test/test.c",
  "file": "/proj/test/test.c"
}
]

"Compile Active File" output:

/usr/bin/cc "" -g -o CMakeFiles/test.dir/test.c.o -c /proj/test/test.c
/proj/test/build$ /usr/bin/cc "" -g -o CMakeFiles/test.dir/test.c.o -c /proj/test/test.c
cc: error: : No such file or directory
