using nrf_drv_config.h

I notice that each dev board has a version of nrf_drv_config.h in the config folder. For my custom target, I want to create my own version of this file where I will modify things such as the specific pins used by the SPI bus. So under the config folder I will have a new folder "my_target" with my customized copy of the header file. But how do I indicate in the project settings that I want to pick up the new custom header file?

To add some context to this, I'm merging the nRF52 BLE peripheral template with the SPI template so my nRF52-based BLE peripheral can control an SPI device. This means my BLE template was originally targeted at the PCA10040, except I want to use different pins for the SPI bus. I copied nrf_drv_config.h from the PCA10040 config folder to start with, of course.

I answered my own question. This is a matter of changing the include path in the C/C++ tab of the project settings. In the template project, this is the very first include path and it points to the folder named for your target board. In my case, I changed that path and it builds correctly.
