Bug#1051650: cmake: Problems finding libraries on Alpha
Package: cmake
Version: 3.26.4-4
Severity: normal
Tags: ftbfs
X-Debbugs-Cc: debian-alpha@lists.debian.org
Many (> 50) have been FTBFS on alpha recently due to
cmake not finding libraries.
This bug is sent against cmake with Cc to the debian-alpha
list to document and track this issue.
Observations:
1. The problem is about not finding a library,
it happens in many packages with many libraries.
2. The problem happens only on alpha.
3. There is no such problem with non-cmake build systems.
4. The problem started after the release of bookworm.
It might be a regression in cmake 3.26 or somewhere else (glibc?).
5. It happens both on the real hardware buildd and on the qemu buildds.
6. The problem does not always happen, it seems to be a race condition.
In the attached files, within 2 hours the same buildd with exactly the same build
dependencies installed had one failure and one success:

When diff'ing these build logs, the first non-trivial difference is
-CMake Error at /usr/share/cmake-3.27/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
- Could NOT find LibSKK (missing: LIBSKK_LIBRARIES)
+-- Found LibSKK: /usr/lib/alpha-linux-gnu/libskk.so
