[Buildroot] [PATCH v2 1/5] package/stellarium: fix qt5serialport dependency

[Buildroot] [PATCH v2 1/5] package/stellarium: fix qt5serialport dependency

[Bernd Kuhls]

qt5serialport is only needed when GPS support is enabled:
https://github.com/Stellarium/stellarium/blob/v25.4/CMakeLists.txt#L623

Please note that we disable telescope support by default so only gpsd
enables the usage of qt5serialport.

A backport to the LTS branches should be considered, adding
qt5serialport as dependency without gpsd support causes the unneeded
build of qt5serialport for stellarium. This situation exists for years
and is not caused by recent upstream changes.

[Buildroot] [PATCH v2 2/5] package/stellarium: add extra downloads

[Bernd Kuhls]

Building Stellarium includes the download of external tarballs during
configure.

This fails with host-cmake during configure stage:

CMake Error at md4c-subbuild/md4c-populate-prefix/src/md4c-populate-stamp/download-md4c-populate.cmake:163 (message):
  Each download failed!

    error: downloading 'https://github.com/mity/md4c/archive/refs/tags/release-0.5.2.tar.gz' failed
          status_code: 1
          status_string: "Unsupported protocol"
          log:
          --- LOG BEGIN ---
          Protocol "https" not supported

  closing connection #-1

due to buildroot commit f87138339b17bc2b1d84c59ea176abb941413550 which
disabled SSL support for host-cmake.

This patch uses _EXTRA_DOWNLOADS to provide these tarball to allow
offline builds.

No autobuilder error was recorded, the build error can be reproduced
with this defconfig:

[Buildroot] [PATCH v2 3/5] package/stellarium: bump version to 26.1

[Bernd Kuhls]

https://stellarium.org/release/2026/04/05/stellarium-26.1.html

Added dependency to qt5svg needed since upstream commit
https://github.com/Stellarium/stellarium/commit/a5c374bfa314a75c19aa65cc758c68517ef608ad
which was added with this release.

This is not correct. qt5serialport would only be pulled as a
dependency of stellarium if BR2_PACKAGE_QT5SERIALPORT=y. So in *any*
case qt5serialport would be part of the build. The only difference is
that it is a build dependency of stellarium for no reason. This is not
that much of a problem and probably doesn't deserve being backported,
so I dropped this paragraph, and applied your patch to master.

Thanks a lot!

Thomas
