^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}

Suggested change

	if self.settings.os == "Windows" and self.settings.compiler == "Visual Studio":
	if is_msvc(self):

and add from conan.tools.microsoft import is_msvc

[SpaceIm]

Suggested change

	self.build_requires("jom/1.1.3")
	self.tool_requires("jom/1.1.3")

[SpaceIm]

could you move build_requirements after validate() please?

Also:

• move config_options & configure before requirements
• use rm_safe to delete fPIC in configure and bump required_conan_version to 1.53.0
• use export_conandata_patches in export_sources
• extract apply_conandata_patches and call it at the beginning of build()
