I want to build QCA for ARM Linux and Qt 4.8
I have successfully compiled OpenSSL 1.1.0 and Qt 4.8.6 for ARM platform
Then I tried to build QCA with cmake. I set paths to qt, openssl and cross-compiler through the toolchain-file and interface of ccmake.

But when I tried to make (verbose=1) I got an error:

After second attempt of make I got such error:

And after third and subsequent attempts of make I got such error:

Why do I get different errors during make? What am I doing wrong? How to cross-build QCA correctly?
The build of Qt uses external library Tslib. Seems that QCA can't find the path to tslib.so (see output of 2nd attempt of make). How should I specify the path to this library?
