You can set flags to give configure scripts or Makefiles a nudge in the right direction. An example of flag setting:
```sh
./configure --prefix=/Users/Dave/Downloads CFLAGS="-I$(brew --prefix)/opt/openssl/include" LDFLAGS="-L$(brew --prefix)/opt/openssl/lib"
./configure --prefix=/Users/Dave/Downloads CFLAGS="-I$(brew --prefix openssl)/include" LDFLAGS="-L$(brew --prefix openssl)/lib"
```
An example using `pip`:
```sh
CFLAGS="-I$(brew --prefix)/opt/icu4c/include" LDFLAGS="-L$(brew --prefix)/opt/icu4c/lib" pip install pyicu
CFLAGS="-I$(brew --prefix icu4c)/include" LDFLAGS="-L$(brew --prefix icu4c)/lib" pip install pyicu

An example of this is:

If you’re curious about the `PKG_CONFIG_PATH` variable, `man pkg-config` goes into more detail.
