Arguments following NAMES cannot include a directory, they must be file names only.
And I follow this. I will happen cannot open file error.
The below is the problem:
Please check first the content of your
_PQXX_INCLUDE variable (e.g. inside the cache file) to see if the find was correct.
I assume that you need to specify the correct file name for the find, which is:
pqxx.h and not just
I can search the library(cache file is correct). But I can’t include the library.
So I rewrite the find_path. It work and can find library.
PATHS "D:/libpqxx/include" )
Please delete your build directory (or at least the cache file).
The variable needs to be a directory, not a file, and this is not the result of this
find_path command. It probably was already set by earlier experiments or you have another find with the same variable.
I have delete build folder for the two method.
Sorry I cannot understand what do you mean. Do you have the example？
This will find the path, which you need to add to your include directory. Which is in fact
I assume this is just an example to understand the find command. If you know the path already and hardcode it, then you don’t need to search for it in the first place.
