Preferential include path in CMake

[Mitsuru]

Dear all,

I use CMake for build system, and define include path of libraries via link_directories.

Here, is there a way to switch the include path preferentially with respect to system's path (c.f. usr/include to an include path I defined)?


Kind regards

When you specify your own include paths, they take precedence over the implementation's. So, if you put in one of those paths a file named iostream, when you #include <iostream> you'll be including that file, not the implementation's iostream.

Dear helios,

Thank you for your reply.
What I told me is, do not use #include <***>, but use #include "***", when selecting our own include directories.

According to it, I will try my project, thank you so much.

If you use quotes instead of angle brackets the compiler will first look for the file in the path relative to the current file. If it can't find it, it will continue looking in the include paths.
In other words, if you expect the file you're looking for to be in an include path then it doesn't make any difference if you use angle brackets or quotes.
