Add dependency for LLVM. Fixes #1611 This adds a depdendncy wrapper for llvm-config based on the wxwidgets dependency. IT handles libs, version, include dir, and the llvm unique concept of components. These components are individual pieces of the LLVM library that may or may not be available depending on the platform. 8 years ago			`project('llvmtest', ['c', 'cpp'], default_options : ['c_std=c99'])`

tests: Improve llvm dependency test coverage 8 years ago			`d = dependency('llvm', modules : 'not-found', required : false)`
			`assert(d.found() == false, 'not-found llvm module found')`

deps: demote LLVM config to instance variable Which fixes trying to use multiple versions of LLVM, and allows simplifying the class somewhat. 7 years ago			`d = dependency('llvm', version : '<0.1', required : false)`
			`assert(d.found() == false, 'ancient llvm module found')`
tests: Improve llvm dependency test coverage 8 years ago
llvm: Add optional modules These will become more relevant later in the series. 7 years ago			`d = dependency('llvm', optional_modules : 'not-found', required : false)`
			`assert(d.found() == true, 'optional module stopped llvm from being found.')`

llvm: fix static linking I left a hack patch in a pull request for LLVM, and the result is that LLVM doesn't link with static builds. The real problem was that some distros have pkg-config for tinfo, other's don't, so the correct solution is to use cpp_compiler.find_library if dependency() fails. 7 years ago			`dep_tinfo = dependency('tinfo', required : false)`
			`if not dep_tinfo.found()`
			`cpp = meson.get_compiler('cpp')`
			`dep_tinfo = cpp.find_library('tinfo')`
			`endif`

llvm: Add support for linking statically This adds support for the static kwarg to the llvm dependency. 7 years ago			`foreach static : [true, false]`
			`llvm_dep = dependency(`
			`'llvm',`
			`modules : ['bitwriter', 'asmprinter', 'executionengine', 'target',`
