I cannot imagine Clion, which lacked proper Autotools/Makefile support a year ago, dominate the embedded world now. Due to the immaturity of LSP, the same doubt applies to VScode.

Eclipse CDT, the long time king in embedded world, has been deliberately hidden from the default list. You have to click 'all results' to see it. Such a nasty trick!

PS: Eclipse can support all project long before LSP/Clion appeared, provided that 'CDT GCC Build Output Parser' is setup properly.
