glm/glm-1.0.1-fix-tests-big-endian.patch
Atri Bhattacharya e33433b9df - Update to version 1.0.1 
* Features:
    + Added C++17 [[nodiscard]] support
  * Improvements:
    + Enables only warnings as errors while building unit tests
    + Added aligned_*vec3 simd support
  * Fixes:
    + Fixed C++ language auto detection build, disable C++98 warnings
      with Clang [gh#g-truc/glm#1235] [gh#g-truc/glm#1231]
    + Fixed GTX_color_space missing <glm/ext/scalar_constants.hpp>
      include [gh#g-truc/glm#1233]
    + Fixed EXT_matrix_transform shear implementation
    + Fixed smoothstep SIMD implementation [gh#g-truc/glm#1222]
- Changes from version 1.0.0
  * Features:
    + Added GLM_EXT_scalar_reciprocal with tests
    + Added GLM_EXT_vector_reciprocal with tests
    + Added glm::iround and glm::uround to GLM_EXT_scalar_common
      and GLM_EXT_vector_common
    + Added GLM_EXT_matrix_integer with tests
    + Added Github Actions
    + Added GLM_FORCE_UNRESTRICTED_FLOAT to prevent static asserts
      when using other scalar types with function expecting floats.
  * Improvements:
    + Added constexpr qualifier for cross product
    + Added constexpr qualifier for dot product
  * Fixes:
    + Fixed incorrect assertion for glm::min and glm::max
    + Fixed quaternion orientation in glm::decompose
    + Fixed singularity in quaternion to euler angle roll conversion
    + Fixed quat glm::pow handling of small magnitude quaternions
    + Fixed glm::fastNormalize build error
    + Fixed glm::isMultiple build error
    + Fixed glm::adjugate calculation
    + Fixed glm::angle discards the sign of result for angles in
      range (2pi-1, 2pi)
    + Removed ban on using glm::string_cast with CUDA host code
- Removed patches
  * glm-0.9.9.8-install.patch, now included upstream
- Added patches
  * glm-1.0.1-fix-install-cmake-files.patch
  * glm-1.0.1-noarch.patch
  * glm-1.0.1-without-werror.patch
- Updated patches
  * glm-0.9.9.8-pkgconfig.patch updated to
    glm-1.0.1-pkgconfig.patch
  * glm-0.9.9.8-fix_tests_big-endian.patch updated to
    glm-1.0.1-fix-tests-big-endian.patch
- Spec file changes
  * Set BuildArch to noarch for devel package as it is a header only
    package
  * Use cmake_build instead of make_jobs
