rpmbuild on CentOS: no such file or directory - centos

Question

I have created a simple RPM on Fedora27 and it worked fine. It just copied files from tar.gz to /usr/bin/.
When I tried to install this RPM on CentOS I got:
# rpm -i RPMS/x86_64/my_rpm-0.0-5.x86_64.rpm --force
error: Failed dependencies:
libc.so.6(GLIBC_2.26)(64bit) is needed by my_rpm-0.0-5.x86_64
So I assumed I will need to create the RPM on CentOS.
But when I do so I get a weird: 'No such file or directory' that I don't get on Fedora27. Here is a sketch of my spec file:
%define _topdir %(pwd)
%define name my_rpm
%define release 5
%define version 0.0
%define buildroot %{_topdir}/%{name}-%{release}-root
BuildRoot: %{buildroot}
Summary: my_rpm
License: -
Name: %{name}
Release: %{release}
Version: %{version}
Source: %{name}-%{version}-%{release}.tar.gz
Prefix: /usr
Group: Tools
%description
This is my_rpm spec file
%prep
%setup -q -n %(arch)/%{name}-%{version}
%install
install -D my_app -t %{buildroot}/usr/bin/my_rpm/
%files
/usr/bin/my_rpm/*
When I try to build the RPM for it I get:
# rpmbuild -v -bb --clean SPECS/bpf.spec
+ install -D app -t /root/rpmbuild/BUILDROOT/my_rpm-0.0-5.x86_64/usr/bin/my_rpm/
install: failed to access '/root/rpmbuild/BUILDROOT/my_rpm-0.0-5.x86_64/usr/bin/my_rpm/': No such file or directory
The same SPEC exactly runs smoothly on Fedora27.
What should I change in it my spec file so that it would work both on Fedora27 and CentOS7? or maybe I can fix my initial problem with Glibc?
EDIT 1
I added the "mkdir -p ..." command under install and the build was successful but it still gives me the same error, that I need Glibc 2.6.
What I don't understand is why during the build it says:
Requires: libc.so.6()(64bit) libc.so.6(GLIBC_2.14)(64bit) libc.so.6(GLIBC_2.2.5)(64bit) libc.so.6(GLIBC_2.26)(64bit) libc.so.6(GLIBC_2.3)(64bit) libc.so.6(GLIBC_2.3.4)(64bit) libc.so.6(GLIBC_2.7)(64bit) libc.so.6(GLIBC_2.9)(64bit) libelf.so.1()(64bit) libelf.so.1(ELFUTILS_1.0)(64bit) rtld(GNU_HASH)
Edit 2(solution)
I got it to work. My executables are compiled C code. So I had to re-compile everything on CentOS and then build the rpm. Now it works on both Fedora and CentOS.
