+Preserve the compiler flags supplied by the EasyBuild toolchain when
+building QUICK.
+The QUICK top-level CMake configuration resets CMAKE_Fortran_FLAGS,
+CMAKE_C_FLAGS, and CMAKE_CXX_FLAGS to empty strings. This hides the
+compiler flags inherited from the parent AmberTools configuration,
+including optimization, architecture-specific, floating-point, PIC,
+MPI include, and other toolchain options.
+Remove these resets so that QUICK inherits the compiler flags provided
+by EasyBuild. QUICK can still append its own compiler-specific and
+target-specific options through its existing CMake configuration.
+Based on a patch by Jinzhe Zeng from the conda-forge AmberTools
+feedstock, commit b9dc271.

+Compare the decompressed contents in the cpptraj gzip regression test.

+The cpptraj general test compares the generated gzip file directly with

+Preserve the EasyBuild Python environment during the install-time pytraj
+build.
+AmberTools constructs the pytraj installation command inside a CMake
+install(CODE) block and inserts PYTHONPATH_SET_CMD immediately before
+invoking setup.py. This replaces the inherited PYTHONPATH and hides
+Python packages supplied by the EasyBuild build environment.
+Pytraj is configured to regenerate its Cython-generated extension
+sources for Python 3.14 compatibility. The install-time setup.py command
+therefore needs access to the external Cython installation. Without it,
+pytraj incorrectly reports that Cython is unavailable and is not
+installed.
+Remove PYTHONPATH_SET_CMD from the install-time command so that pytraj
+inherits the EasyBuild PYTHONPATH, including Cython and the other Python
+dependencies. The installation prefix remains controlled by the
+existing setup.py installation arguments.
