../configure fails

[hale2bopp]

What operating system (Linux, Windows, …) and version?
MacOS 10.14.5

What did you do?
I cloned the repo using :
$ git clone https://github.com/Juniper/grpc-c.git

I installed required dependencies as described in the gRPC docs.

Then I did
$ cd grpc-c
$ autoreconf --install
$ git submodule update --init
$ ./builddeps.sh

then -
$mkdir build && cd build
$ ../configure
Error!

What did you expect to see?
Something beautiful!
I expected to see the grpc-c compile nicely.

What did you see instead?
Here, I get the following error :

checking for stdio.h... yes
checking for stdlib.h... (cached) yes
checking for string.h... (cached) yes
checking sys/param.h usability... yes

configure: error: Could not find grpc.h anywhere, install grpc

I have installed grpc.

Issue caused due to unused variable warning - error - line 57 in create_channel.cc
As a result grpc build failed, but didn't prevent protobufs build, so I didn't realize that it had failed for a while.
Commented out the two lines: line 56 and 57.

// internal::GrpcLibrary
// init_lib; // We need to call init in case of a bad creds.
