libusb detection fails when x-compiling for Android

[mambrus]

When cross-compiling for Android detecting libusb will fail. Instead of detecting the correct one or ending up here https://github.com/Nuand/bladeRF/blob/master/host/libraries/libbladeRF/CMakeLists.txt#L189

...the hosts libusb is found instead. Build log follows (only last lines):

:

This doesn't occur when I'm building libbladeRF for ARM with Yocto, via the bladeRF recipes in meta-sdr.

I'll look to get you the following from that build, so we can compare and contrast.

• CMake logs
• Resulting CMakeCache.txt
• Build logs

Closing this issue, as there's been no activity in a number of years. If you or anyone else experiences issues w/ building on Android (or even a success, heh...) please let us know.

Thanks :)
