CalcMySky is a software package that simulates scattering of light by the
atmosphere to render daytime and twilight skies (without stars). Its primary
purpose is to enable realistic view of the sky in applications such as
planetaria. Secondary objective is to make it possible to explore atmospheric
effects such as glories, fogbows etc., as well as simulate unusual environments
such as on Mars or an exoplanet orbiting a star with a non-solar spectrum of
radiation.

- Use CFLAGS and CXXFLAGS instead of CMAKE_CXX_FLAGS and CMAKE_C_FLAGS.
- Use MODCMAKE_LDFLAGS instead of CMAKE_EXE_LINKER_FLAGS
- Fix broken builds with CMake 3.23
Remove the webkit/webengine-wxneeded hack in cmComputeLinkInformation.cxx
and add USE_WXNEEDED=Yes to all cmake webkit/webengine consumer.
Background knowledge about the "hack":
It searches for webkit/webengine (lower-case search) in all link-entries for
EXECUTABLE/SHARED_LIBRARY targets. If the search match it adds
"-Wl,-z,wxneeded".
Feedback, help and OK sthen@ Thanks!
Skyfield computes positions for the stars, planets, and satellites in
orbit around the Earth. Its results should agree with the positions
generated by the United States Naval Observatory and their Astronomical
Almanac to within 0.0005 arcseconds (half a "mas" or milliarcsecond).
Skyfield can compute geocentric coordinates or topocentric coordinates
specific to your location on the Earth's surface.
While Skyfield itself has no dependency on the AstroPy library, it's
willing to accept AstroPy time objects as input and return results in
native AstroPy units.
This is a recent short-period ephemeris published by the Jet Propulsion
Laboratory. It requires only 27 MB of storage and is specially accurate
with respect to the position of Earth's Moon.
