It doesn't work for headers distributed through nimble.
For some users the path will be
`{.header:"/home/cheatfate/.nimble/pkgs/foopkg-0.1.0/headers/fooheaders.h".}`
and others will have
`{.header:"/Users/mratsim/.nimble/pkgs/foopkg-0.2.0/headers/fooheaders.h".}` `
There is probably a way through staticRead and then staticExec to copy the
headers but I don't see an obvious non-hacky way.
