building with cmake - can't detect shared libraries

Hello guys, I have bumped into this issue when building this custom library for my own fork :

it relies on the "protobuf" library as dependency, of which I rewrote the Makefile :

to distinguish the actual EXE and the libraries from each other. The fact is that with the new definition of the
STAGING_DIR_HOST env variable set as :


the shared libraries are not detected anymore but instead, the native host ones are ! Take a look at the log :

Since the cmake builds are always peculiar ones, I was wondering if I have to pass an additional switch the the cmake configure step to reflect the
new changes in the trunk itself, any ideas on that ?

this behaviour in my opinion will break all the future library-dependent cmake builds...thanks in advance...

Regards, Arturo

Thank you Felix, your fix has solved my issue. A simple rebase on the latest trunk did the trick.

The issue can now be closed. Thanks, Arturo.
