+Subject: [PATCH] CMake: fix build without ocl-icd
+
+If not using ocl-icd (in this case, I was using dev-libs/opencl-icd-loader),
+OCL_ICD_INCLUDE_DIRS and friends won't be defined and CMake bails out
+with an error:
+```
+-- Configuring done
+CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
+Please set them or make sure they are set and tested correctly in the CMake files:
+/var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL/OCL_ICD_INCLUDE_DIRS
+   used as include directory in directory /var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL
+   used as include directory in directory /var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL
+/var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL/devices/OCL_ICD_INCLUDE_DIRS
+   used as include directory in directory /var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL/devices
+/var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL/devices/basic/OCL_ICD_INCLUDE_DIRS
+   used as include directory in directory /var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL/devices/basic
+/var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL/devices/pthread/OCL_ICD_INCLUDE_DIRS
+   used as include directory in directory /var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL/devices/pthread
+/var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL/devices/topology/OCL_ICD_INCLUDE_DIRS
+   used as include directory in directory /var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/CL/devices/topology
+/var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/llvmopencl/OCL_ICD_INCLUDE_DIRS
+   used as include directory in directory /var/tmp/portage/dev-libs/pocl-3.0/work/pocl-3.0/lib/llvmopencl
+```
+
+This broke in 3ecda3b294d70e4f915ad141d669f4bc1298f606.
+
+To fix, just check if the value is truthy before using (this is enough
+for checking if it's NOTFOUND).
