file INSTALL cannot find mariadb_cancel.3

I'm attempting to update the mariadb-connector-c rpm in Fedora to 3.4.2 and hitting the following error:
```
CMake Error at redhat-linux-build/man/cmake_install.cmake:46 (file):
file INSTALL cannot find
"/home/orion/fedora/mariadb-connector-c/mariadb-connector-c-3.4.2-build/mariadb-connector-c-3.4.2/man/mariadb_cancel.3":
No such file or directory.
```
Many other .3 man pages are built, but not that one. I also see:
```
