Let’s say I’ve made two OOT projects called gr-first and gr-second. I  
want to link gr-second against gr-first, but CMake isn’t finding it.

gr-first/CMakeLists.txt seems to install a helper file:  
$PREFIX/lib/cmake/first/firstConfig.cmake

In gr-second/CMakeLists.txt, I add a line:

find\_package(first)

But this does not work. I also tried

include(firstConfig)

find\_package(first)

I guess I can hack something together using an example like gr-osmosdr,  
which depends on gr-iqbalance. Although if possible, I’d like to use the  
default helper file and get that working, since that’s the whole point  
of having a helper file. Any hints?

Thanks,

Sean

?Strange. It is now working for me, and I don’t know what I did to break  
or fix it.
