cmake-native: fix to function correctly in case of eSDK
Our eSDK is expected to provide traditional SDK's functionality. But
for cmake, it could not function well in eSDK.
This problem is discovered by the assimp.py test case. The error message
is as below.
testsdkext/tmp/sysroots/x86_64/usr/lib/libz.so: error adding symbols: file in wrong format
collect2: error: ld returned 1 exit status
The problem is about cmake-native being unable to find the correct lib.
nativesdk-cmake has solved this problem. So make use of the solution to
solve the eSDK problem.
