pyopencl cache doesn't care about #incude

[petRUShka]

I share some code between opencl files. Because of OpenCL 1.1 format easiest way is inclusion common cl code into both of cl files like this:

common.cl

void test(void){
  return;
}

kernel.cl:

#include "common.cl"

__kernel void test_kernel(__global int *result)
{
  test()
}

If I modify test in common.cl pyopencl doesn't see it and use cached version of common.cl. Even if I delete test from common.cl pyopencl doesn't see it. It's quite dangerous because for example I spent a lot of time trying to find an error that was in this cache issue.

It tries to detect changed include files:

It's apparently failing to do so in your case. Can you shove some print statements into this code to figure out what's going wrong?

[petRUShka]

I understand the reason! I collect my cl files in cl/ subdir of project root. So I call build with argument "-I /home/user/opencl/cl", and your cache subsystem doesn't see it. So cache subsystem should care about -I option to fix this issue.

[inducer]

It also does try to see -I options. :)

It already understands ["-I/some/where"] (note:no space!) and ["-I", "/some/where"]. 15bc505 adds handling for your style. See if that fixes it. Repopen if not.
