add build option for constrained node ops and make sure everything is now target-optimised in all configurations (allows debugging on the target using the debug build config) link libatomic if we're targeting 486 link libatomic.a if we're targeting windows idk what the hell MSVC does for -arch:IA32 we already set the c++14 flag early on strip target selection flags from MSVC builds and clang-cl c++14 does not propagate to compile tests 2019-08-27 13:47:44 +00:00			`link_libatomic()`

cmake refactor Refactors many things in cmake to improve and simplify: - don't use variable indirection for target names; target names are already a variable of sorts. (e.g. ${UTIL_LIB} is now just lokinet-util). cmake/basic_definitions.cmake is now gone. - fix LTO enabling to use the standard cmake (3.9+) LTO mechanism rather than shoving a bunch of flag hacks through link_libraries and add_compile_options. This also now enables LTO when building a shared library (because previously the -flto hacks were only turned on in the static code for some reason). - build liblokinet as either shared library or static library, but not both. Building both makes things more complicated because they had different names (lokinet-shared or lokinet-static) and seems pointless: you generally want one or the other. Now there is just the liblokinet target, which will be shared or static depending on the value of BUILD_SHARED_LIBS. - Simplify lokinet-cryptography AVX2 code: just build one library, and add in the additional AVX2 files when possible, rather than building two and needing to merge them. - Compress STATIC_LINK and STATIC_LINK_RUNTIME into just STATIC_LINK. It makes no sense to use one of these (_RUNTIME) on Windows and the other on non-Windows when they appear to try to do the same thing. - remove a bunch of annotations from `endif(FOO)` -> `endif()`. - move all the tuntap compilation code (including OS-specific source file selection) into vendor/CMakeLists.txt and build tuntap as an intermediate OBJECT library rather than keeping a global variable in 5 different files. - move release motto define to root cmake; it made no sense being duplicated in both unix.cmake and win32.cmake - fix add_log_tag to not stomp on any existing source compile flags with its definition. Also use proper compile definition property instead of cramming it into compile flags. - make optimization/linker flags less hacky. There's no reason for us to force particular optimization flags because the cmake build type already does that (e.g. -DCMAKE_BUILD_TYPE=Release does -O3). Not doing that also silences a bunch of cmake warnings because it thinks "-O0 -g3" etc. are link libraries (which is reasonable: that's what the code was telling cmake they are). - sets the default build type to RelWithDebInfo which gives us `-O2 -g` if you don't specify a build type. - Move PIC up (so that the things loaded in unix.cmake, notably libuv, have it set). - Add a custom `curl` interface library that carries the correct link target and include paths for curl (system or bundled). 2020-05-17 19:41:48 +00:00			`if (${CMAKE_SYSTEM_NAME} MATCHES "OpenBSD")`
