Hi, I'm working on a project in which a base linux distribution is built using yocto while a set of proprietary components is built with the generated SDK (-c populate_sdk).
These components use cmake for building. While they build just fine when the 'cmake' command is invoked from command-line, as soon as there's a fork() and execve() in between (e.g. when cmake is invoked from a script or even when I tried tracing it with strace), the build fails on finding any external library: -- Could NOT find ZLIB (missing: ZLIB_LIBRARY) (found version "1.2.8") CMake Error at cmake/external_dependencies.cmake:10 (message): Could not find zlib Call Stack (most recent call first): CMakeLists.txt:109 (include) The 'found' message is there because it eventually 'found' my host's header as visible in the strace output[1]. The target arch is core2-64 while the host is x86_64. Both host and target dirs are present in sysroots/. What's clear when browsing the strace output is that the headers are not searched for in the right directory which would in this case be sysroots/core2-64-poky-linux/usr/include/ but in /sysroots/x86_64-pokysdk-linux/ instead. I initially thought this to be a problem with the project's CMakeLists.txt but it seems fine given the fact that it builds when used manually. Any idea what could be the culprit here?
